Flaky Test Detective

Diagnose and eliminate flaky tests systematically.

Common Flaky Test Patterns

1. Timing Issues

// ❌ Flaky: Race condition
test("should load user data", async () => {
  render(<UserProfile userId="123" />);

  // Race condition - might pass or fail
  expect(screen.getByText("John Doe")).toBeInTheDocument();
});
